Children's and adolescents' perception of the authenticity of smiles.
Recently, Thibault and colleagues described the Duchenne marker as a cultural dialect for the perception of smile authenticity. The current study had the goal to follow up on this finding and to investigate the cues that French Canadian children use to evaluate the authenticity of smiles from members of three ethnic groups. The authenticity of six smiles differing in intensity and presence of orbicularis oculi (Duchenne marker) was rated by 1206 children from 4 to 17 years of age. No differences were found as a function of encoder group. All children perceived medium Duchenne smiles as more authentic than equally intense medium non-Duchenne smiles. Furthermore, results suggest a decrease in the reliance on intensity across the age span. Younger children use the intensity marker along the whole continuum to infer authenticity. In contrast, older children (14- to 17-year-olds) rated all smiles that did not contain the Duchenne marker as roughly equally low in authenticity.
